<p>如果你想要将你压缩的数据组织到一个子目录下，只需简单的将文件路径包含到文件名中即可:</p>
<div class="highlight-ci"><div class="highlight"><pre><span class="nv">$name</span> <span class="o">=</span> <span class="s1">&#39;personal/my_bio.txt&#39;</span><span class="p">;</span>

<p>允许你压缩一个已经存在于你的服务器上的目录（包括里面的内容）。该方法的参数为目录的路径，Zip
类会递归的读取它里面的内容并重建成一个 Zip 文档。指定目录下的所有文件以及子目录下的文件都会被压缩。
例如:</p>

<p>默认情况下，Zip 文档中会保留第一个参数中指定的目录结构，如果你希望忽略掉这一大串的树形目录结构，
你可以将第二个参数设置为布尔值 FALSE 。例如:</p>

<p>向你的服务器指定目录下写入一个 Zip 编码文档，该方法的参数为一个有效的目录路径，后加一个文件名，
确保这个目录是可写的（权限为 755 通常就可以了）。例如:</p>
<div class="highlight-ci"><div class="highlight"><pre><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">zip</span><span class="o">-&gt;</span><span class="na">archive</span><span class="p">(</span><span class="s1">&#39;/path/to/folder/myarchive.zip&#39;</span><span class="p">);</span> <span class="c1">// Creates a file named myarchive.zip</span>
</pre></div>
</div>
</dd></dl>

<dl class="method">
<dt id="CI_Zip::download">
<tt class="descname">download</tt><big>(</big><em>$filename = 'backup.zip'</em><big>)</big><a class="headerlink" href="#CI_Zip::download" title="永久链接至目标">¶</a></dt>
<dd><table class="docutils field-list" frame="void" rules="none">
<col class="field-name" />
<col class="field-body" />
<tbody valign="top">
<tr class="field-odd field"><th class="field-name">参数:</th><td class="field-body"><ul class="first simple">
<li><strong>$filename</strong> (<em>string</em>) -- Archive file name</li>
</ul>
</td>
</tr>
<tr class="field-even field"><th class="field-name">返回类型:</th><td class="field-body"><p class="first last">void</p>
</td>
</tr>
</tbody>
</table>
<p>从你的服务器上下载 Zip 文档，你需要指定 Zip 文档的名称。例如:</p>
<div class="highlight-ci"><div class="highlight"><pre><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">zip</span><span class="o">-&gt;</span><span class="na">download</span><span class="p">(</span><span class="s1">&#39;latest_stuff.zip&#39;</span><span class="p">);</span> <span class="c1">// File will be named &quot;latest_stuff.zip&quot;</span>
</pre></div>
</div>
<div class="admonition note">
<p class="first admonition-title">注解</p>
<p class="last">在调用这个方法的控制器里不要显示任何数据，因为这个方法会发送多个服务器 HTTP 头，
让文件以二进制的格式被下载。</p>
</div>
</dd></dl>

<dl class="method">
<dt id="CI_Zip::get_zip">
<tt class="descname">get_zip</tt><big>(</big><big>)</big><a class="headerlink" href="#CI_Zip::get_zip" title="永久链接至目标">¶</a></dt>
<dd><table class="docutils field-list" frame="void" rules="none">
<col class="field-name" />
<col class="field-body" />
<tbody valign="top">
<tr class="field-odd field"><th class="field-name">返回:</th><td class="field-body">Zip file content</td>
</tr>
<tr class="field-even field"><th class="field-name">返回类型:</th><td class="field-body">string</td>
</tr>
</tbody>
</table>
<p>返回使用 Zip 编码压缩后的文件数据，通常情况你无需使用该方法，除非你要对压缩后的数据做些特别的操作。
例如:</p>
<div class="highlight-ci"><div class="highlight"><pre><span class="nv">$name</span> <span class="o">=</span> <span class="s1">&#39;my_bio.txt&#39;</span><span class="p">;</span>
<span class="nv">$data</span> <span class="o">=</span> <span class="s1">&#39;I was born in an elevator...&#39;</span><span class="p">;</span>

<span class="nv">$this</span><span class="o">-&gt;</span><span class="na">zip</span><span class="o">-&gt;</span><span class="na">add_data</span><span class="p">(</span><span class="nv">$name</span><span class="p">,</span> <span class="nv">$data</span><span class="p">);</span>

<span class="nv">$zip_file</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">zip</span><span class="o">-&gt;</span><span class="na">get_zip</span><span class="p">();</span>
</pre></div>
</div>
</dd></dl>

<dl class="method">
<dt id="CI_Zip::clear_data">
<tt class="descname">clear_data</tt><big>(</big><big>)</big><a class="headerlink" href="#CI_Zip::clear_data" title="永久链接至目标">¶</a></dt>
<dd><table class="docutils field-list" frame="void" rules="none">
<col class="field-name" />
<col class="field-body" />
<tbody valign="top">
<tr class="field-odd field"><th class="field-name">返回类型:</th><td class="field-body">void</td>
</tr>
</tbody>
</table>
<p>Zip 类会缓存压缩后的数据，这样就不用在调用每个方法的时候重新压缩一遍了。但是，如果你需要创建多个 Zip
文档，每个 Zip 文档有着不同的数据，那么你可以在多次调用之间把缓存清除掉。例如:</p>
<div class="highlight-ci"><div class="highlight"><pre><span class="nv">$name</span> <span class="o">=</span> <span class="s1">&#39;my_bio.txt&#39;</span><span class="p">;</span>
<span class="nv">$data</span> <span class="o">=</span> <span class="s1">&#39;I was born in an elevator...&#39;</span><span class="p">;</span>

<span class="nv">$this</span><span class="o">-&gt;</span><span class="na">zip</span><span class="o">-&gt;</span><span class="na">add_data</span><span class="p">(</span><span class="nv">$name</span><span class="p">,</span> <span class="nv">$data</span><span class="p">);</span>
<span class="nv">$zip_file</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">zip</span><span class="o">-&gt;</span><span class="na">get_zip</span><span class="p">();</span>

<span class="nv">$this</span><span class="o">-&gt;</span><span class="na">zip</span><span class="o">-&gt;</span><span class="na">clear_data</span><span class="p">();</span>

<span class="nv">$name</span> <span class="o">=</span> <span class="s1">&#39;photo.jpg&#39;</span><span class="p">;</span>
<span class="nv">$this</span><span class="o">-&gt;</span><span class="na">zip</span><span class="o">-&gt;</span><span class="na">read_file</span><span class="p">(</span><span class="s2">&quot;/path/to/photo.jpg&quot;</span><span class="p">);</span> <span class="c1">// Read the file&#39;s contents</span>
